USB Connectors-Tips and How they Work

USB has come quite a long way since its conception in the year 1995, and it was initially designed to simplify how the users controlled peripherals and transferred data. Before then, he main interfaces that were used to transfer data and control peripherals were the parallel and serial connectors that used different protocols to perform this task. The connectors were often clumsy and required lining up numerous pins to fit the holes in the female end connectors. They also offered slower data transfer rates as compared to the USB connector.

USB is an abbreviation that stands for Universal Serial Bus. USB connectors are used to connect different types of USB cables with all standard compatible USB ports. The primary work of the USB cables if for data transfer. The data transfer speeds may vary from 12Mbps in version 1.1 and up to 480 Mbps in version 2.0. USB ports also can be used to connect numerous computer accessories by replacing their specific cables with USB connectors.

The Working Mechanism of the USB
USB devices require low and medium bandwidths and can be plugged in and our anytime even when the system is running. When the computer enters power saving mode, the USB device is automatically put to sleep mode. When the system powers up, it enquires all the devices and assigns an address for the devices connected. The computer then finds out from each device the type of data transfer that it needs to perform. When removing the USB, you do not need to reboot or switch off the system.

The universal service bus offers a simple standard way of connecting up to 127 devices to the computer. You will find that generally, the USB connector is found in the back of the computer, but there are others that have it at the front. Soon after plugging in, the operating system will automatically search and discover the new device. If you happen to have the driver disk along with it, insert it when the operating system asks for it. If the device had been previously connected, the system would start the communication process soon after plugging it in. USB devices come with their inbuilt cable and have an “A” connection on it. If there is no in-built cable, the device will accept the USB “B” connector. The type “A” connectors head upstream while the “B” connectors head downstream and link to devices. To avoid confusions, the standard USB uses “A” and “B” connectors.

As mentioned earlier, the USB interface replaced a wide range of previous interfaces such as the serial and parallel ports and individual power chargers for portable devices. USB connectors are now commonly used with devices like network adapters and portable media players as well as video game consoles and smartphones.
